How to create a table or diagram based on multiple rows and columns

hi,

maybe it is late or whatever might be the reason, but i do not seem to figure out a seemingly simple case.

I have an excel sheet with contact persons (rows) and for each person we need to document the date we contacted each one of them per stage (columns). I attached an illustrateive file.

No i want to keep track of the progress and would need some kind of pivot table telling me the number of (count) contacts per stage (shown in rows) and per date (shown in columns). Alternatively, it would also be helpful to take a look at the data in a bar chart. both would help me to see at a glance how many persons we got to stage 1, 2 and/or 3 at a certain date.

How can I realize that? would i need to create a mapping table next to the dataset or is there another way?

Regards
Kian
